Field experiment was conducted to determine the effectiveness of five bio-insecticides against onion thrips, Thrips tabaci on two onion cultivars for two consecutive years (2011/12and 2012/13). Most of the tested bio-insecticides caused significant (P< 0.05) reduction of thrips compared to the control in all the observation dates except 7days after treatment in 2012. Interaction results showed that Lastraw has significantly (P<0.05) decreased the density of thrips and increased the yield of Onion White. Onion White gave higher benefit-cost ratio when treated with Lastraw (3.06:1) than azadirachtin 0.15% (2.60:1) in 2011/12.
